Zeolite clinoptilolite catalyst powder will be produced by the support of the water, drought, erosion and environment development headquarter to eliminate nitrogen oxides from the chimney of various air polluting industries. 

According to the public relations and information center of the Vice-Presidency for science and technology affairs, the term "environmental catalysts" encompasses different uses of catalysts applied to reduce environmental pollution. Some of these catalysts play an important role in converting harmful chemicals that harm the environment into compounds that have no negative impact on the natural cycle of living organisms. Therefore, they are of paramount importance. In this respect, the water, drought, erosion and environment development headquarter supports the production zeolite clinoptilolite catalyst powder to eliminate nitrogen oxides from the chimney of various air polluting industries.
